The aim of this work was to obtain more detailed insight into the role of Au-support interactions in the creation of catalytic performance of Au/Ce0.75Zr0.25O₂ in CO oxidation. The Ce0.75Zr0.25O₂ oxide and Au/Ce0.75Zr0.25O₂ catalysts were synthesized, characterized by BET, XRD, HRTEM, AAS, TPR-H₂, and tested in CO oxidation. An approximate evaluation of H₂ consumption for the surface reduction of the studied samples was estimated, applying the model developed by Johnson and Mooi, based on the qualitative relationship between the magnitude of the capping oxygen and BET surface area.
